Printed textile fabric



Patented Jan. 26, 1937 UNlTED STATES PRINTED TEXTILE FABRIC Alfred M.Schwarzschild, Berlin, Germany No Drawing. Application December 11,1934, Serial No. 756,983. In Germany November 6 Claims.

It is well known in the printing industry that when printing fabricseither by relief or discharge printing or by other printing processesthe print penetrates through to the back of the fabric. The printedpattern, of course, appears more or less washed out on the back of thefabric so that only one side of the fabric can be exposed. Attempts haveindeed been made to remedy this disadvantage by making the fabric whichis to be printed as thick as possible. Apart, however, from the waste ofmaterial caused thereby and the impossibility of making general use ofheavy fabrics of this nature for all purposes, the disadvantage that thepattern penetrates through to the back of the fabric was not obviated bythis means. Even if the printing be undertaken with great care and evenif the fabric is woven so as to be double-sided, experiments which havebeen made by the inventor have proved that the pattern is neverthelessstill clearly visible on the back of the fabric even if not to such apronounced extent. In any case the back of the printed fabric cannot beused.

According to the present invention, a doublesided textile fabric, forexample a woven or knitted fabric, of which one side consists of threadsof different materialfrom that of the threads on the other side, isemployed for printing. For example, the material or threads on one sideof the fabric may consist of natural silk and on the other side ofcotton. Again, one side of the fabric may consist of wool and the otherside of artificial silk or threads of two different kinds of artificialsilk, for example acetate silk and viscose silk, may be employed onopposite sides of the fabric. If one side of a fabric of this nature isprinted on it is found that the printed pattern, even if heavilyprinted, does not penetrate through at all to the back of the fabric,which consists of threadsof a different material, so that the materialof the back of the fabric can be dyed as desired or can be allowed toremain white. By this means there is obtained a fabric both sides ofwhich can be used and of which one side exhibits a printed pattern whilethe other side, on the other hand,-may be of any desired shade, andeither of a single color, or, if desired, of several colors, or it mayexhibit a shot effect. Particularly pretty effects are obtained if theback of the fabric is dyed in the colour of the background of theprinted pattern. Obviously, any kinds of patterns may also be applied tothe side which is not printed on.

A fabric of this kind has not-previously been known, it is a noveltywhich has many uses, in

particular for fashionable garments and the like. Any penetration of theprint to the back of the fabric which was hitherto thought to beunavoidable is'entirely excluded for the first time by means of theinvention.

It is, of course, known that the different capabilities of differentkinds of threads for absorbing different colors can be utilized for theproduction of colour effects. In such cases, however. only mixed fabricswere made use .of, for example fabrics of which the warp and weft werecom-' posed of different kinds of threads. When a mixed fabric of thiskind is dyed, the dye is taken up by one of the kinds of thread betterthan by the other. The present invention, on the other hand, isconcerned with a "double-sided fabric one side of which is printed andthe other side can be dyed as desired owing to the fact that the printedpattern is not visible on it.

The method in accordance with the invention is, of course, suitable alsofor bands or any other kind of textile products.

I claim:

1. The herein described method of producing a printed textile fabrichaving a printed pattern visible on only one side thereof, which methodcomprises producing a double-sided textile fabric of which one sideconsists of a thread material having by nature a different dyeingafllnity from the thread material which forms the other side of thefabric, and printing a pattern on one side of the said fabric with a dyehaving affinity for the thread material of the said side withoutaffecting the reverse side of said material.

2. The herein described method of producing a printed textile fabricwhich method comprises producing a double sided textile fabric of whichone side consists of a thread material having by nature a differentdyeing aflinity from the thread material which forms the other side ofthe fabric, printing a pattern on one side of the said fabric with a dyehaving aflinity for the thread material of the said side withoutaffecting the reverse side of said material and then printing a patternon the other side of the fabric with a dye having affinity for thethread material of latter side without affecting the thread material ofthe first printed side.

3. A double-sided textile fabric of which the threads on the two sidesconsist of materials having diflerent natural dyeing affinities andhaving one side printed in 'a pattern with a dye having afflnity'for thethreads of that side, the

threads of the other side being unaffected by the dye on the saidprinted side of the fabric.

4. A double-sided textile fabric of which the threads on the two sidesconsist of materials having difierent natural dyeing aflinities andhaving one side printed in a pattern with a dye having aflinity for thethreads 01' that side, and the other side printed in a pattern with adifferent dve having amnity for the threads oi the latter side,penetration of the respective dyes from one side to the other beingabsent, due to the diflerent i0 aflinities of said two sides of thefabric.
